Our LAN has two DHCP servers, one giving 10.x.x.x addresses and one giving 192.168.x.x addresses. The network guys refuse to fix the obvious misconfiguration, and in Linux I have successfully resolved the problem by adding the following line to /etc/dhcp/dhclient.conf, which ignores any DHCP offers from the rogue DHCP server:
reject 192.168.100.1;
How can I ignore the rogue DHCP server in OSX?
